Lab Profile

Description

The Carderock Division consists of approximately 3,800 scientists, engineers and support personnel working in more than 40 disciplines ranging from fundamental science to applied/in-service engineering. We are the Navy's experts for maritime technology. Headquartered in West Bethesda, Md., the Division houses world-class facilities and laboratories. A major operating site in Philadelphia is recognized as the center for naval machinery. The Division also conducts research and development at several remote sites across the country. As a major component of the Naval Sea Systems Command the Carderock Division provides cradle-to-grave support for its technical products over an enormous range of scientific areas related to surface and undersea platforms. The Division addresses the full spectrum of applied maritime science and technology, from the theoretical and conceptual beginnings, through design and acquisition, to implementation and follow-on engineering. This includes all technical aspects of improving the performance of ships, submarines, military water craft, and unmanned vehicles, as well as research for military logistics systems. In addition, the Division is uniquely chartered by Congress to support America's maritime industry.

Mission

The mission of the Carderock Division is to provide: research, development, test and evaluation, fleet support, and in-service engineering for surface and undersea vehicle hull, mechanical, and electrical (HM&E) systems and propulsors; logistics research and development; and support to the Maritime Administration and maritime industry.

Active-radar-assisted passive composite imagery for aiding navigation or detecting threats

Description:

Typical inventive practice provides for electronic communication of a computer with a display, an active radar device (for transmitting target-location data and environmental data), a light measurement device (for transmitting visual light data), and passive imaging devices covering bands in the visual, infrared (MWIR and/or LWIR), and millimeter wave regions of the electromagnetic spectrum. Inventive software in the computer's memory establishes operational modes. Each operational mode is defined at least by a predominant environmental (obscuration and lighting) character, ascribes modal indices to individual imaging devices, and carries its own multispectral image fusion algorithm (which, pursuant to the ascribed modal indices, attributes weights to the imaging data from the respective imaging devices). The inventive software aims the imaging devices toward the target, selects an operational mode (based on the environmental data), and executes the image fusion algorithm associated with the selected operational mode so that a fused multispectral image is displayed.

Interactive pedestrian routing method

Description:

The present invention's network-based directions-provision methodology typically features the establishment of two ranking schemes that reversely parallel each other. The personal ranking scheme ranks all permitted persons in terms of the degree of access permission with respect to the variously ranked regions of a facility; the lower the personal rank, the fewer the regional ranks to which the person is permitted access. The regional ranking scheme ranks all accessible regions in terms of the degree of access permission with respect thereto by the variously ranked permitted persons; the higher the regional rank, the fewer the personal ranks that are permitted access to the region. According to typical inventive practice, a permitted person logs in to request directions, within the facility, from an original location to a destination location; the directions given (textual and/or graphical) are the optimal directions that are consistent with the personal rank of the requestor.

Periscope universal hull packing

Description:

An embodiment of an inventive periscope hull packing system includes a sleeve, a first ring, a first spring-loaded hull seal, a second ring, a second spring-loaded hull seal, and a gland. The first ring is below the sleeve. The first spring-loaded hull seal is below the first ring. The second ring is below the first spring-loaded hull seal. The second spring-loaded hull seal is below the second ring. The gland and the second spring-loaded hull seal, which is housed by the gland, are below the second ring. The sleeve and the gland each have, on the inside circumference, a composite lining affording a lubricious surface for contacting the periscope. Each composite lining is composed of a resinous matrix and a filler lubricant (such as particles or short discontinuous fibers of polytetrafluoroethylene). Each spring-loaded hull seal is characterized by an elastomeric shell and an elastomeric O-ring spring for energizing the shell.

Quad shaft contrarotating homopolar motor

Description:

A homopolar motor features radially inner and outer pairs of axially aligned rotor drums to which axially aligned drive shafts are respectively connected and extend therefrom through an outer motor housing to drive a corresponding number of propellers located in axial spaced relation to each other outside of the housing for rotation about a common axis. A magnetic shield is fixedly mounted within the housing to enclose the rotor drums within a magnetic field established by disk and ring magnets positioned within the radially inner pair of the rotor drums. Current collector brushes maintain electrical contact between the rotor drums and a source of DC electrical energy supplied through a power input tube to the magnetic shield from a location between opposite axial ends of the housing. The drive shafts journaled within the housing extend from either opposite axial ends of the housing or from only one axial end of the housing to the propellers.

System and method for modifying the net buoyancy of underwater objects

Description:

Buoyancy is controlled in a tethered object by pumping fluids, either of a first or second specific gravity, from an external source into either a first or second containment chamber to change the respective volumetric capacities of the first and second containment chambers. The containment chambers are configured such that the second chamber is at least partially enclosed within the first chamber. The second chamber is configured to expand and retract within the first chamber, which has a fixed housing. Expansion or contraction of the second chamber results in a corresponding inverse change in a volumetric capacity of the first chamber. The fluid chambers may be separate or contained within the same housing, and may be located on a towing vessel. Sensor data from the tethered object's environment may be used to control the transfer of fluid to the first and second chambers.

System for changing the attitude of linear underwater sensor arrays via neutrally buoyant fluid transfer

Description:

The attitude of a submerged array of sensing elements can be changed using a fixed quantity of transferable ballast fluid having density different than water. In one embodiment, a non-rigid array of sensor elements is equipped with two expandable reservoirs connected between a flexible conduit which allows the ballast fluid to be transferred back and forth. Pumping fluid between the two reservoirs causes one reservoir to expand while the other contracts. Due to the density difference between the pumped fluid and water, the difference in volume between the two expandable reservoirs causes a shift in the center of buoyancy of the array system. The center of buoyancy in this way becomes offset from the center of gravity of the array system, causing a shift in the attitude of the array. The array can be trimmed, using positively or negatively buoyant static elements, to achieve a specific orientation for given volume ratios between the two expandable reservoirs, and so by controlling the volume ratio, multiple orientations can be selected.
